TypeError: невозможно прочитать свойство 'release' undefined в магазине ngrx с angular только в производственной сборке

У меня возникла проблема, но только после производственной сборки во время выполнения. Теперь я не уверен, ошибка ли это или я делаю ошибку. Я получаю сообщение об ошибке «TypeError: Cannot read property 'release' of undefined». " в консоли (браузере), если я загружу следующий функциональный модуль с помощью ngrx (во время выполнения):

    import { AccountDto } from '../../../dto';
import * as fromAccountActions from '../actions/account.actions';

export interface AccountState {
  loading: boolean;
  loaded: boolean;
accountItems: AccountDto[];
}

export const initialState: AccountState = {
  loading: false,
  loaded: false,
  accountItems: []
};


export function accountReducer(
  state = initialState,
  action: fromAccountActions.AccountActions
): AccountState {

  switch (action.type) {
    case fromAccountActions.LOAD_ACCOUNT: {
      // console.log(action.type);
      return { ...state, loading: true };
    }

    case fromAccountActions.LOAD_ACCOUNT_FINISHED: {
      console.log('Finished: ' + action.payload);
      return {
        ...state,
        loading: false,
        loaded: true,
        accountItems: action.payload
      };
    }

    case fromAccountActions.LOAD_ACCOUNT_FAILED: {
      return {
        ...state,
        loading: false,
        loaded: false,
        accountItems: []
      };
    }

    default:
      return state;
  }
}

export const getAccountItems = (state: AccountState) => state.accountItems;
export const getAccountLoading = (state: AccountState) => state.loading;
export const getAccountLoaded = (state: AccountState) => state.loaded;

index.ts в редукторах

import * as fromReducer from './account.reducers';
import { ActionReducerMap } from '@ngrx/store';
import { createFeatureSelector } from '@ngrx/store';

export interface AccountState {
  account: fromReducer.AccountState;
}

export const reducers: ActionReducerMap<AccountState> = {
  account: fromReducer.accountReducer
};

export const getAccountState = createFeatureSelector<AccountState>('account');

account.selectors.ts

import { createSelector } from '@ngrx/store';
import * as fromReducer from '../reducers/account.reducers';
import * as fromFeature from '../reducers';

export const getCompleteAccountState = createSelector(
  fromFeature.getAccountState,
  (state: fromFeature.AccountState) => state.account
);
export const getAccountLoading = createSelector(
  this.getCompleteAccountState,
  fromReducer.getAccountLoading
);
export const getAccountLoaded = createSelector(
  this.getCompleteAccountState,
  fromReducer.getAccountLoaded
);
export const getAllAccountItems = createSelector(
  this.getCompleteAccountState,
  fromReducer.getAccountItems
);

account.module.ts

import { CommonModule } from '@angular/common';
import { NgModule } from '@angular/core';
import { FormsModule } from '@angular/forms';
import { TranslateModule } from '@ngx-translate/core';

import { ThirdPartyModule } from '../thirdParty/thirdParty.module';
import { SharedModule } from './../shared/shared.module';
import { AccountListComponent } from './account-list/account-list.component';
import { AccountRoutesModule } from './account.routes';
import { StoreModule } from '@ngrx/store';
import { EffectsModule } from '@ngrx/effects';
import { reducers, AccountEffects } from 'app/+account/store';

@NgModule({
  imports: [
    CommonModule,
    FormsModule,
    SharedModule,
    AccountRoutesModule,
    ThirdPartyModule,
    TranslateModule,
    StoreModule.forFeature('account', reducers),
    EffectsModule.forFeature([AccountEffects])
  ],

  declarations: [AccountListComponent],
  providers: [],
  exports: []
})
export class AccountModule {}

Помощь будет очень признательна. Спасибо
